If the cable is ok.....

On two speedos I took apart, each uses a magnetic drive setup to make
the needle move. I'm about certain all the Vanagon speedos are the
same in this respect. The magnetic wheel is connected to the cable. It
spins a cup shaped pickup wheel which in turn moves the spring loaded
needle (pick up wheel turns slower than the drive wheel. The magnetic
relationship introduces a type of gear reduction it seems)

WAG, but maybe cold weather has an effect on these and/or other speedo
parts? eg. the grease used on various parts is fairly thick.

A bunch of pics of my '85 Vanagon speedometer in pieces:
